CHARLES A. BRYANT, OF WAKEFIELD, MASSACHUSETTS, ASSIGNOR TO THE SCOVILLMANUFACTURING COMPANY, OF WATERBURY, CONNECTICUT.

TACK-FASTENED BUTTON.

SPECIFICATION formingpart of Letters Patent No. 656,508, dated August21, 1900.

Application filed u e 12; 1900- To all whom it may concern:

Be it known that I, CHARLES A. BRYANT, a citizen of the United States,residing at Wakefield, in the county of Middlesex and State ofMassachusetts, have invented a certain new and useful Improvement inTack-Fastened Buttons, of which the following is a full, clear, andexact description.

' The object of this invention is to provide a combined anvil andhub-reinforce for a button of that class which has a bottomless shank orhub and which is secured to a garment by a tack.

In carrying out my invention I form from sheet metal, preferably steel,an inverted cup having a flanged lip, and this lip is bent backparallel, or nearly so, with the cup or hollow portion, so as to leavean annular space. This annular space receives the bottomless shank orhub of the button, with the cup or hollow portion extending up withinthe shank or hub, and when thus assembled the parts are pressed togetherand shaped to form an integral anvil and hub -reinforce having aninternal chamber within which the point of the tack is upset or clenchedand concealed and a flange externally surrounding the shank or hub.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a sideelevation of one form of my button. Fig. 2 is a cross-section of abutton-blank. Fig. 3 is a cross-section of the cupped anvil andhub-reinforce. Fig. 4 is a cross-section of the anvil and hub-reinforceready for ap-. plication to the button-blank of Fig. 2. Fig. 5 is across-section showing the button-blank of Fig. 2 and the anvil andhub-reinforce of Fig. 4 in position for assembling. Fig. 6 is across-section of the finished button. Fig. 7 is a cross-sectionillustrating the manner of setting or fastening the button to a garmentby a tack.

The button-blank, if an open-face button is to be made, has a flange aand a bottomless shank or huh I), produced in any approved manner, or ifa covered or closed-face button be desired its back or collet isproduced with a bottomless shank or hub in an analogous 5o manner. Thecombined anvil and hub-reinforce is formed from a disk of metal, saysheet Serial No. 20,038. (No model.)

steel, and the anvil portion 0 is drawn with a surrounding flange d,Fig. 3. This flange is then bent back or returned parallel, or nearlyso, with the anvil portion 0, as shown in Fig. 4, so as to leave a spaceor pocket e between the bent flange and the cup or hollow or anvilportion 0. The shank or hub is inserted in this pocket with the anvilportion projecting within the shank or hub, and then by means ofsuitable tools or dies the parts are bent and closed together, and thusrigidly united, and the outer portion is contracted,

so as to complete the chamber f for the reception of the tack-point,leaving in the inturned bottom of this chamber an opening g for thepassage of the tack-point, with a surrounding Wall of three thicknessesof metal, whereby the button is thoroughly reinforced against allstrains incident to the upsetting or clench- 7o ing of the tack h andfollowing from the use of the garment to which the button is applied.

It will be observed that the point of the tack is anchored wholly withinthe shank br hub of the button and that said shank or hub is reinforcedto resist or withstand the strains imposed by setting and using thebutton, and hence it follows that a very strong and durable button isproduced.

As is shown in the drawings, the flange d extends up into the bead whichusually surrounds the hub oi an open-face button, and this may bedesirable for strength, alinement, and appearance, but is not absolutelynecessary, and hence the said flange may be relatively longer or shorterthan the cupped portion c, and, further, the said cupped portion may beof a length to project beyond the face of the button or fall below it,the preferred construction being the latter and as shown in thedrawings.

By reason of the final shape of the combined anvil and hub-reinforce andthe fact that it adds its thickness to the finished button it suhservesto that extent, at least, the 5 purpose of a spacer.

This invention differs from prior buttons in that the anvil andhub-reinforce are a unit both before and after application to the button blank or head instead of being separate pieces, and it differs alsofrom those prior buttons in which the anvil and spacer are integral inthat it is dependent upon its assembling with the button blank or headfor its final operative shape and union with such blank or head, and inthe preferred construction is located wholly on one side of the back ofthe button--that is to say, within its shank or hub-and by reason ofthis last fact my button may be used with the tacks now in common useand needs not a tack of special length. Moreover, my combined anvil andhub-reinforce may be very economically produced and with simple toolsand as readily and economically assembled with the buttonblank.

What I claim is- 1. A button, having a combined anvil and hub-reinforcecomposed of a cupped portion which is adapted to upset and retain thetackpoint, anda returned flange integral therewith, between which partsthe shank or hub of the button is secured, substantially as described.

2. A button, comprising a button-blank, having a bottomless shank orhub, an anvil located within such shank or hub and having an integralflange externally embracing such shank or hub, the outer end of theshank or hub and the anvil and its flange being contracted so as to forma tack-point passage into a clenching-chamber within the anvil,substantially as described.

3. A tack fastened button, including a shank or hub, and a combinedanvil and hubreinforce applied to such shank or hub, and having its tackreceiving and clenching portion located'within the shank or hub, and areturned flange arranged outside of the shank or hub, the said shank orhub and the combined anvil and hub-reinforce being united by pressureand the outer end contracted to form a tack-entrance and aclenching-chamber above such entrance, substantially as described.

In testimony whereof I have hereunto set my hand this 4th day of June,A. D. 1900.

CHARLES A. BRYANT.
